How to convert hexadecimal number to Binary in java
In above example, It uses the IntStream
class of Java 8 java.util.stream
package to convert each character in the hexadecimal string to its binary counterpart. The mapToObj
method is used to map each integer to a binary string using the Integer.toBinaryString
method. Then, the map
method formats each binary string to have four digits by padding it with zeros if necessary. At last, the reduce
method joins all the binary strings into one string.
